  • This salt battery harvests osmotic energy where the river meets the sea

    Updated: 2024-04-24 15:15:49
    Estuaries -- where freshwater rivers meet the salty sea -- are great locations for birdwatching and kayaking. In these areas, waters containing different salt concentrations mix and may be sources of sustainable, 'blue' osmotic energy. Researchers report creating a semipermeable membrane that harvests osmotic energy from salt gradients and converts it to electricity. The new design had an output power density more than two times higher than commercial membranes in lab demonstrations.

  • Critical minerals recovery from electronic waste

    A nontoxic separation process recovers critical minerals from electronic scrap waste.

  • More economical and sustainable rechargeable batteries

    Updated: 2024-04-22 04:06:37
    Lithium salts make batteries powerful but expensive. An ultralow-concentration electrolyte based on the lithium salt LiDFOB may be a more economical and more sustainable alternative. Cells using these electrolytes and conventional electrodes have been demonstrated to have high performance. In addition, the electrolyte could facilitate both production and recycling of the batteries.

  • The biggest barrier to a vibrant second-hand EV market? Price

    Updated: 2024-04-19 17:27:43
    As early adopters of electric vehicles (EVs) trade up for the latest models, the used EV market is beginning to mature in the United States. Yet many potential buyers, particularly low-income drivers, are skeptical of EV's conveniences and are put off by the price.

  • Mess is best: Disordered structure of battery-like devices improves performance

    Updated: 2024-04-18 20:51:55
    The energy density of supercapacitors -- battery-like devices that can charge in seconds or a few minutes -- can be improved by increasing the 'messiness' of their internal structure. Researchers used experimental and computer modelling techniques to study the porous carbon electrodes used in supercapacitors. They found that electrodes with a more disordered chemical structure stored far more energy than electrodes with a highly ordered structure.

  • Neutrons rule the roost for cage-free lithium ions

    Updated: 2024-04-16 04:53:16
    Scientists using neutrons set the first benchmark (one nanosecond) for a polymer-electrolyte and lithium-salt mixture. Findings could boost power and safety for lithium batteries.

  • Pyrite, also known as fool's gold, may contain valuable lithium, a key element for green energy

    Updated: 2024-04-15 15:04:58
    The technology revolution and development of new renewable energy resources is driving demand for lithium to new heights, but it is not a common mineral. Scientists say they have found lithium in an unexpected place; fool's gold, or pyrite, deposits.

  • Discovery brings all-solid-state sodium batteries closer to practical use

    Updated: 2024-04-11 17:02:48
    Researchers have developed a mass synthesis process for sodium-containing sulfides. Mass synthesis of electrolytes with high conductivity and formability is key to the practical use of all-solid-state sodium batteries, thought to be safer than lithium-ion batteries and less expensive, as sodium is far more plentiful than lithium.

  • BESSY II: How pulsed charging enhances the service time of batteries

    Updated: 2024-04-09 04:39:09
    An improved charging protocol might help lithium-ion batteries to last much longer. Charging with a high-frequency pulsed current reduces aging effects, an international team demonstrated.

  • Drawing inspiration from plants: A metal-air paper battery for wearable devices

    Updated: 2024-04-03 17:06:35
    Drawing inspiration from the way plants breathe, a group of researchers has created a paper-based magnesium-air battery that can be used in GPS sensors or pulse oximeter sensors. Taking advantage of paper's recyclability and lightweight nature, the engineered battery holds promise for a more environmentally friendly source of energy.

  • Unleashing disordered rocksalt oxides as cathodes for rechargeable magnesium batteries

    Updated: 2024-04-03 17:06:24
